Natural Benzaldehyde

Natural Benzaldehyde  

Natural Benzaldehyde is a natural aromatic aldehyde obtained by retro-aldol cleavage (alkaline hydrolysis/oxidation) of cinnamaldehyde, the main component of Chinese cinnamon oil (cassia oil). It features an intense, authentic bitter almond, cherry and nutty aroma, ranking as the second most widely used natural flavor globally (after vanillin).

1. Basic Information

  • Chemical Name: Benzaldehyde (Benzoic Aldehyde)
  • CAS Number: 100-52-7
  • Molecular Formula: C₇H₆O
  • Appearance: Colorless to pale yellow clear liquid
  • Aroma: Strong bitter almond + black cherry + nutty notes with spicy undertone; highly diffusive
  • Purity: ≥98.5% (GC) natural grade
  • Solubility: Slightly soluble in water; soluble in ethanol, ether, chloroform, oils, propylene glycol

2. Source & Production Process

  • Natural Source: Chinese Guangxi cinnamon oil (cassia oil, cinnamaldehyde ≥90%); sustainable alternative to scarce bitter almond source (≈20 tons/year globally)
  • Process (Green Natural Route):Cinnamon oil → Rectification (cinnamaldehyde) → Alkaline-catalyzed retro-aldol reaction → Crude benzaldehyde → Vacuum rectification → High-purity natural benzaldehyde
  • Features: 100% botanical origin, no hydrocyanic acid residue, pure aroma, high safety, Kosher/Halal certified

3. Main Applications

1）Food Flavoring (Primary Use)
  • Flavor profiles: Bitter almond, cherry, peach, plum, nut, cocoa, chocolate, caramel
  • Confectionery & bakery: Hard candy, chocolate, biscuits, pastries, almond cookies (enhance nutty/almond notes)
  • Beverages & liqueurs: Liqueurs, rum, brandy, soft drinks, fruit wines (boost cherry/almond top notes)
  • Tobacco & sauces: Tobacco flavors, BBQ sauces, meat products (deodorize, enhance flavor depth)
2）Fragrance & Personal Care
  • Floral/fruity notes: Cherry, almond, peach, vanilla, oriental, aldehydic top & heart notes
  • Fine perfumes & home fragrances: High-end perfumes, aromatherapy (enhance sweet fruity, nutty warmth, diffusion)
  • Oral care: Toothpaste, mouthwash (freshen breath, mild almond sweetness)
  • Soaps & body care: Soaps, detergents, body washes (classic almond + cinnamon warm scent)
3）Pharmaceuticals & Intermediates
  • Flavor correction: Mask bitter taste of pharmaceuticals, improve compliance
  • Pharmaceutical synthesis: Key intermediate for antibiotics, antihistamines, sedatives, antitumor drugs
  • Topical preparations: Medicated oils, creams (antibacterial, soothing, perfuming)
4）Fine Chemicals
  • Fragrance intermediates: Synthesis of cinnamic acid, cinnamyl alcohol, coumarin, benzoic acid, benzyl alcohol
  • Organic synthesis: Intermediate for dyes, pesticides, photosensitive materials
  • Electroplating & materials: Brighteners, resin curing agents

4. Key Advantages

  • Natural & Safe: FEMA 2127, FDA GRAS, GB2760 approved; cyanide-free, high natural purity
  • Unique Aroma: Bitter almond + cherry + nut complex note, hard to replicate synthetically
  • Resource Advantage: World’s top Guangxi cinnamon industry, stable capacity & cost-effective
  • Market Demand: Global food-grade natural benzaldehyde demand >3,000 tons/year; cassia oil route is mainstream supply
